Using CCM for the Prediction of Sorption Curves under Varying Ionic Strength Conditions: Reply to Some Comments

In response to the comments of J. Lützenkirchen (237, 297 (2001), J. Colloid Interface Science), it is pointed out that the criticized model is not intended to provide a complete description of the system studied (Cs on silica-magnetite). Rather, it is a simplification of a complex natural system. The accuracy of the obtained predictions requires further investigation. Copyright 2001 Academic Press.
